Slight Formatting Problem with Feed Tip on Syndication Page

At least on Firefox, the example in the tip uses an entity '%2B' instead of the comma ',' It shows up as:

... here is a feed for <a href="/taxonomy/term/11%2B9%2B10/0/feed">

Instead of:

... here is a feed for <a href="/taxonomy/term/11,9,10/0/feed">

One possible hack is adding the following after line 130 in the module:

$output = str_replace("%2B",",",$output);
